I collected a few hundred LPs and a few thousand 45's and all kinds of equipment. Everything makes a difference M1 speaker cables, phono stage, interconnects, isolation transformer.... My system was to the point where I was limited by the daily variation in my own hearing and recording quality. I could swap in a different "quality" amp or speakers and instantly hear how bad they really are. I traded my best amp to my brother (a tube unit based on a kit) and currently run an adcom in going to do some upgrades on because it sounds awful, but I completely lack the serenity to sit in the sweet spot and listen to music. I listen to almost all my music at work now from FLACs on a Yamaha and Bose 301's.
